Harbor Canyon
Five stops tuned to sit together without fighting — #004e64 ink anchors the set, #73bfdb opens it up, and #007998, #3294b4, #56a2be cross the middle in a analogous arrangement. Harbor Canyon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
